ANLY06002 2019 DATA PROCESSING, MOLECULAR GRAPHICS AND INSTRUMENTATION
This module deals with laboratory instrumentation and applications of information technology for forensic and analytical science.
Students will learn the basic operation, calibration and data processing capabilities of a range of instrumentation used for forensic analysis. Instrumentation used will include uv-visible, infrared, atomic absorption and chromatographic instrumentation.
Other software applications/techniques used will include drawing two-dimensional chemical structures, determining basic chemical parameters with software (i.e. determination of molecular weights, verifying chemical reactions, etc.) and using a spreadsheet to simulate titrations.
The teaching methods used will be a combination of lectures, self-study, labs, tutorials, and any combination of discussion, case study, problem-solving exercises and computer-based learning.
On completion of this module the learner will/should be able to;
Describe the components of selected general purpose analytical instrumentation
Operate, optimise and calibrate selected general purpose analytical instrumentation
Process and present analytical data using spreadsheets.
Collect and process data from modern scientific instrumentation
Teaching and Learning Strategies
This module will be delivered fulltime. Teaching methodology will employ a problem based learning (PBL) approach. This will be supplemented with introductory lectures, laboratory exercises, independent learning and directed learning. This approach is expected to address student learning needs. Moodle will be used as a repository of educational resources and as a means of assessment (e.g. quizzes, uploading assignments and journals). Self-assessment tests and other forms of formative assessment are provided to students to check their own progress towards achieving the learning outcomes of the module and to motivate learning.
Module Assessment Strategies
This module is 100% Continuous Assessment. Laboratory skills and report-writing ability are assessed as part of the practical work performed during the module. Regular summative tests are used to encourage engagement with the module, monitor progress and provide feedback. The continuous assessment will include the following elements: assessment of performance in laboratory exercises (30%); assignments (15%) and practical reports (15%); At least four assessments of combined practical and theoretical ability will be carried out during the semester (40%).
Repeat written assessment and assignments.
1. Describe the components of selected general purpose analytical instrumentation
UV-Visible spectrometers including overlay scans
Flame Atomic absorption spectrometers
Ion-selective electrodes, potentiometers
Automatic titrators e.g. Karl Fischer method
Regarding Forensic Science Society (FSS) component standard describe the application and theory relating to a the range of analytical techniques that are available to the forensic scientist, understand the parameters involved in method selection and be able to provide a forensic strategy and an analytical strategy for a given scenario.
2. Operate, optimise and calibrate selected general purpose analytical instrumentation
Practical implementation learning outcome number 1 above
Operation, calibration, safety, care and maintenance of analytical instrumentation
Data processing of infrared and uv‑visible spectral data
Regarding the FSS component standard it is important to demonstrate an understanding of the theory relating range of analytical procedures, specifically within the forensic context.
Regarding the FSS component standard demonstrate competence in operating a range of modern analytical instruments and be conversant with the use of related computer software
3. Process, chart and present analytical data using spreadsheets.
Presenting scientific data with an Excel spreadsheet( significant figures, number formats, absolute and relative addressing, creating formula, plotting scientific data)
Processing of titrimetric data using an Excel spreadsheet.
Determination of titration end-points using derivative plots
Grans plots an Excel spreadsheet.
Determination of pKa from titration data an Excel spreadsheet.
Regarding the FSS component standard evaluate and interpret data from equipment applied to a range of forensic examinations.
4. Utilise molecular graphics applications to both create and study chemical structures
Use Biovia Draw or equivalent two-dimensional molecular structural drawing software to reinforce chemical concepts, terminology and structural display formats.
Create Kekule, condensed and shorthand structures using Biovia Draw
Use Biovia Draw to provide feedback on structures including valency, molecular weights and IUPAC names
Use Rasmol to examine in 3-D chemical structures of simple molecules including standard display formats(wireframe, sticks, ball and stick, spacefill), CPD (Corey, Pauling and Koltun) colouring schemes and export of structures between applications for reporting purposes
Use Rasmol to determine bond lengths, bond angles, torsion angles and other molecular features
